Table C is a function because there is one x-value for every y-value.
Because the order doesn't matter on where each person sits use the combinations formula:
C = n! / (r!(n-r)!)
Where n is the total number of people and r is the number of chairs.
C = 6! / (4!(6-4)!)
C = (6*5*4*3*2*1) / ((4*3*2*1(2*1))
C = 720 / (24*2)
C = 720 / 48
C = 15
There are 15 different arrangements.
<span>This is an example of the substitution property of equality, meaning that if pq = 3, you may substitute 3 for pq in another related equation. So if pq+rs=5 is true, then 3+rs=5 is true as well.</span>
5187 apples to be exact and if you need me to explain why let me know
Cairo's cost is modeled by 45 + 24h
Tarantino's is modeled by 30h
For h = 6:
Cairo = 45 + 24*6 = 189
Tarantino = 180
For h = 7
Cairo = 45 + 24*7 = 213
Tarantino = 210
For h = 10
Cairo = 45 + 24*10 = 285
Tarantino = 300
